As illustrated, thedrain valve is closed but if its stem be turned clockwise as viewed in Fig. 10, from the position there shown, the valve will be, opened.

The sliding discharge pipe 30 is adapted to be manually moved up and down. When positioned as shown in Fig. l itliesin what is hereinafter called Fill position and the upper end of pipe 50 lies high enough above the .upper end of overflow pipe 28 so no liquid can enter it during any normal operation of the apparatus. The-deflector 29- directs the pumped liquid away from the open end of pipe 30. This pipe 30, which is located coaxially with respect to the measuring receptacle, is adaptedto be moved front Fill. position vertically downward to, and held in, a plurality of positions in each of which it, is ellectiveto discharge a predetermined measured quantity, viz, that volume of liquid containethin the receptacle between thetop of the overllow:pipe;28 and. the top of the dischargopipe 30. :The. latter is adaptedto be moved .byfawhandle 61 by. which a vertical rod 62-ma'y. bezmoved; Suchrod passes vertically"upwardseth'rough .a suitable'stnliing box in.hase.-21 (Fig. 5 and intothe niea'suring-I receptacle; being dispo'scd directly iii-frantic]? discharge pipe-30..

The member 68 at its upperfend is secured by cap screws 69 (Figs. 6 and 7 to two laterally spaced; ears T0 whichjasbest shown in Figs. at and 9, project forwardly from a clamp member 7l,thelatterjand a companion member 72 encircling the centrally located pipe 32 and being clamped thereto by bolts as indicated The operating rod (32 passes freely between the spaced cars it) as shown in Figs. 9 and ll. The lower end of member ()5 is similarly secured tothe i'ront member 7;) of a two part clamp (Figs. 8 and 10), which encompasses, and bound to, the overflow pipe to at a point just above the manifold 5?. the member .15 is provided with a centrally located, vertically extending slot Tl, through which the rectangular arm (i5 projects thigs. F) and U} and in which it is guided. The ends of slot T-lare closed and the length of the slot is such as to admit of the desired extent ol.- vertical travel ol discharge pipe 5U. in back ojl' channel member (38 is a rod 75, having its a.\ 'is disposed in parallel relation with-that of the discharge pipe. 'lhis rod 75 is fixed at its ends, the lower end being -reeeived in clamp 73 (Figs 5 and .10). ind the upperend in one of the ears 70 offront clamp 71- (Figs. 5 and 11). The hub. 64, at the base of the discharge pipe operatingrod (32, carries a laterally. projecting car 70 (Figs. 11 and 12) .which encircles. and is slidingly engaged with rod 75, to function as a furtheuguide for; tlie c l;iscliarge piper In order to hold the latter in various-predetermined vertical positions, a -.serieso t'v quantity stops are "provided any one of. which may be swung into thev path of the arm 65 to limit its downwardmovement. Asbest; shown .in Fig.0, there-are nine such stops, designated TIT-and mounted end to. end in abutting relation -on acommon rod 78.. Eacl st 0p- 77 is .frec; to,- turn on rod .78 throughout- .an angle of" about .180 degrees. (see-also Fig- 9)? from a. position wherein it i presents no obstruction to-the. passageof arm 65 toqa position inwhich it crossesslot Hand is adapted to arrest arm (i5-,\ vhe n.it,5is.. lowered. {Each stopis providedwith an ad justablepart 79 with which .arm 65: 81 gages,such pal-1:79 being. adjustable; and commonly scalable for the usual reasons.

. A spring 80 is mounted in a recess in each stop '-7,7,' ;as illustrated in connection with; the upper stop, and adapted to create a-fric-. tion on rod .7 8, tending to hold the stop in the positions;to which it maybe moved.- Themed Z8 is. .n'1ounted at, its ends. in upper andlowen bearings Stand 82. which are cured to channel 68. -Conveniently, the up; per. bearing 81 is provided with a bushing 83 which is used asa means of holding the quantity stops against axial movement.- The bushing is drivendown in bearing 81 until it abuts the upper stop 7'1 and until the several stops have been moved into abutting relation. A pin 84 is then passed through the bearing, bushing and rod to preserve the ad- Jeo lBU

justme'nt. The nine stops 7'? may be consecutively marked from 1 to".9 in a descending scale to indicate gallons or any other suitable quantity. \Vlien arm 65 abuts the part 79 of a stop 78, say that marked for example, the upper end of discharge pipe 30 will be lowered below the upper end of overflow pipe 28 just far enough so that live gallons of liquid can be drawn from receptacle through the discharge pipe. When arm 65 is engaged with other stops of the series, other measured quantities correspondin to the numbers on the stops, can be similarly delivered. For the tenth gallon, or other unit quantity, a fixed stop 8-l (Fig. 4) is mounted on the back of channel 68 and extends across slot 74 to define the extreme lower limit of travel of arm (3? in slot 74.

Means are also provided for registering the quantities of liquid discharged from the measuring receptacle through discharge pipe 30. Such means takes the form of a counter or cumulative register 85, (shown in'Figs. 6, 7 and 9) which is or may be of the Veeder type and operated by certain movements of the slidingdischarge pipe. Inasmuch as the register is of a well known type; detailed description is not required.

= It will suffice tosay that, when its operating shaft 86 is turned in a counter-clockwise direction, as viewed in Fig. 8, the register will be operated and, when this shaft is turned in the opposite direction, the register will not be operated. Shaft 86 has lixed to its other en'd a five;pointed star wheel 87 and the latter, when turned one 'fifth ofa revolution-in a counter-clockwisedirection, will operate register 85 and register one unit.

' The register is'fixedto' an arm 88 (Fig. 9),

secured to'the hub fi i whereby'the register is bodily moved when the discharge pipe is moved. The starfwheel, assliown iii-l ig. 8,' moves in apath adjacent and along one side-of channel 68 and projectinginto this nth-are a series of pins 89 which are ad justably fixed as indicated in Figs. 8 to let, to said side face of the channel in longitudinally spaced relation. There are ten of such pins, one for each of the quantity stops. One pin89' is locatedopposite each of the nioi' able stopsand the tenth pin is located at a point above the uppermost stop 77. In lowering the discharge pipe; these pins 89 serve toflsuccessii ely turn the star wheel 87 in a clockwise direction-so that regis'-- tel 8 5'is not operated. On the upward moi ement of pipe 30, the star wheel is successiv'ely turned by the pins89 iii the proper dirctio'n'to operate the register and as arm passes by on'e'quantity stopaftei" another,

each such increment of upward moveii'ient is counted on the register85.

' It isto be notedthat, it the pipe :10 is lowered, even slightly, below any one of the movable quantity stopsthe counter will be so operated as to i -egister a quantity corresponding to that designated by the next quantity stop therebelow. Say, for example, the arm (14 is carried below the nine gait lon stop but not tothe ten gallon stop, then a point ol the star wheel is brought into position below the lowermost of the pins 89 so as to be operated thereby 0n the return stroke of arm (35. On such stroke ten galltms will be registered even though only nine and a fraction were dispensed. The quantities are in a sense registered in advance so that the pipe -30 cannot be manipulated withoutregistering atleast all that is discharged. That more than the quantity discharged may be registered in cases where arm 30 is-positioned between the stops an'insurance against the operator cheating the owner of the apparatus. The operator is supposed always to move arm 30 into abutment with some one stop and if he does so the correct quantity is registered. If he does not do so', then'more is'registered than is dispensed and, as the proprietor uses this register to check the honesty of his employee, the latter will be held accountable for the extra quantity registered but not dispensed; Consequently, this provision tends to force the employee to set the dis- 1 chargepipe in the proper and contemplated manner.

An extra pin 90, called; the eleventh i)ln,: ispro'vided on channel 68 at the uppercndof the path of movement of the register."

This pin 90 merely insures that= tlie sltar wheel is-prop'erly positioned at the end of each dispensing operation so as to function properly on a succeeding operation.-"-Pin' -90 forces one point ofth estar: (the for-- wardly project-ing-'one')- to' lie exactly hori zontal is-shown Fig. wheir th'e meteris moved tot-he upper limit of'its'stroke', in the event-that it net-iilieady s'o-positioned.
